Hey, sorry if this has been covered, I searched but obviously there are a ton of OMP threads.
Anyone ever thought of switching to an S4 13B 4-line OMP on an 13B-REW? Or better yet, drilling and tapping the REW OMP for 2 extra lines? (Which it appears it may have been designed for initially?
I don't have one in front of me to take apart and confirm, unfortunately).
Now you are probably saying, okay... but what will you do with the extra injectors? Well, a 4-port LIM like the one from Xcessive -- provided you have retained the factory dual fuel rail setup -- leaves you with two empty ports to the primary runners. A little fabrication and these ports could easily accommodate oil injectors. Best of all, on the S4 13B, the 2 additional oil injectors are placed in almost the same place.
Reasonable questions to ask:
-Would the pump be able to supply the extra 2 lines?
Not sure... PFC or other EMS may be needed to have it functioning optimally. (This is assuming the 13b-REW pump could be modified)
-Why were the extra lines removed from the 13B-REW to begin with?
No idea... the Renesis went back to 4 lines but all 4 went to the apex seals, as many of you know.
-Wouldn't one set of side seals/one side of the housing get more lubrication than the other by using only the primaries?
Yes, but would would you rather both sides receive nothing, or one side receive something? Also, this *was* a factory implemented system at one point, so it can't be that bad, right?
The mod would be used in conjunction with a separate 2-stroke oil feed. Not sure if I would premix but a pretty minimal ratio would probably suffice with this setup, which would make the fuel injectors happy.

lol. I'm just a guy that likes rotaries and loves theorizing with like minded folks. Sorry for wasting your time if y'all have been down this road already.
I'm eager to hear your insights, thanks.
